The SCORing Atopic Dermatitis (SCORAD) index was developed in 1993 by the European Task Force on atopic dermatitis. The SCORAD was developed using statistical methods to standardize the assessment of atopic dermatitis and its severity. The evaluation system was chosen for its ease of use in outpatient clinics.
The calculator returns a SCORAD index value. It is one of the most commonly used tools to assess the severity of atopic dermatitis and eczema. The SCORAD calculator uses the extent and the intensity of five types of lesions and dryness, as well as subjective symptom ratings for itching and sleeplessness to return an index value.
Each part of the body is assigned a percentage value and in total they form 100 percent of the area of your body. This is also known as the body surface area (BSA).
Add the percentages for the extent of the disease in each part of your body. Enter this total value, which is between 1 and 100, for the extent of the disease. This value represents the surface area of the body that is affected by the disease.
The intensity of the disease is measured by assigning values to five types of lesions and dryness.
Select values between 0 and 3 for the intensity. A value of 1 indicates mild intensity, 2 indicates moderate intensity, and 3 indicates severe intensity. In the absence of any lesions or dryness, enter 0.
Rate the subjective symptoms of itching and sleeplessness on a scale of 0 to 10. Both itching and sleeplessness are measured with input from the patient. A rating of 0 specifies an absence of symptoms and a rating of 10 specifies the worst symptoms ever experienced, averaged over the prior three nights.
The total index value is calculated out of a total of 103. The scores for the extent and intensity are weighted and added to the subjective symptom score to return this index value.
The SCORAD index value represent the severity of the disease.
These index values can then be used to determine a treatment regimen.
